Technical Field

[0001] The utility model relates to the technical field of hollow square piles, in particular to a prestressed concrete hollow square pile. Background Art

[0002] Hollow square piles are hollow cylindrical slender concrete precast components made by prestressing technology and centrifugal forming. They are mainly composed of square pile bodies, end plates and steel sleeves. Square piles are divided into prestressed concrete and prestressed high-strength concrete according to concrete strength grade and wall thickness. Square piles are code-named PC and prestressed high-strength concrete square piles are code-named PHS.

[0003] The existing prestressed concrete hollow square piles are overall long, so they are not convenient to transport and require longer transportation vehicles to transport. In addition, due to their length, they are prone to collision during transportation, causing damage to the square piles. The damaged square piles cannot be used and can only be scrapped.

[0020] Embodiment 2:

[0021] The technical solution is basically the same as that of the first embodiment, except that Figure 3 As shown, a rotating plate 9 for limiting the extension block 8 is rotatably connected to the extension block 8, and a slot for placing the rotating plate 9 is provided on one side of the hollow square pile 1. The depth of the slot is the same as the thickness of the rotating plate 9, and the shape of the slot is equal to that of two mirror-image rotating plates 9. The rotating plate 9 is inserted into the slot to prevent the extension block 8 from rotating.

[0022] Embodiment three:
